The right form of magnesium for tired calves

When you have logged mile after mile on hard asphalt in the autumn chill, your calves often protest as night falls. To give muscles the conditions they need to relax, you need a bioavailable compound that cells can actually absorb. Many pharmacy shelf products contain cheap magnesium oxide, a compound with low bioavailability that often acts as a mild laxative rather than a muscle relaxant. Our focus is on magnesium bisglycinate, where the mineral is bound to two molecules of the amino acid glycine.

Criteria to check on the back of the bottle

When reviewing the ingredients list, look for specific details that reveal raw material quality and purity:

• Chelate bond: Check that it explicitly states bisglycinate and not a blend diluted with oxide.
• Elemental amount: Check the amount of pure magnesium per capsule relative to total weight.
• Capsule material: Choose capsules made from pure plant cellulose without unnecessary colorants such as titanium dioxide.

Common shortcuts in cheap supplements

A common method among large-scale manufacturers is to label the front of the bottle with bisglycinate, while blending magnesium oxide into the powder to push up elemental levels at a low ingredient cost. This leads to poorer absorption in the small intestine and can cause stomach cramps at bedtime.

How to dose after your evening workout

Take the capsules roughly 45 minutes before bedtime with half a glass of lukewarm water. The glycine in the compound has a calming effect on the nervous system while magnesium helps muscle spindles release tension from the day's training.
